the adhesive slayer 8 of the drum, and are carried with the drum While the paper band Apasses a roller 23 and is Wound up on the roller or pulley 24:.

The further treatment of the adhered leaves is the same as before described.

Fig. 3 shoivs the employment of an endless steel band l26 as movable support, passing through the trough 9 containingad- 1,0 hesivmaterial.n The end-run of this bandK 1s then arranged horizontally or in the same direction With the transport band 15.

In the same manner a paper tape 27 (Fig. 4) of a material proof against the adhesive material used (parclimentized paper or the like)n1ay be employed, this paper tape being unwound from a pulley 28 guided by rollers and finally Wound up on the rotating and driven. pulley 29. When the Whole paper tape is unwound from the pulley 28 and wound up on the pulley 29, these pulleys must'be replaced vby others.

Instead of applying the adhesivematerial by the roller 7 (Figs. 1 and 2), or instead of carrying the movable band lthrough the trough with the adhesive material (Figs. 3 and 4) the adhesive material may be suppliedv by the pressure of air, vapor, 0r a screw 32 or the like in a receptacle 31 situ- L` ated above the band (Fig. 5) and provided AIon the under side with a slotor opening 33. The modifications as illustrated in Figs. 3

to l5 contain all devices for applying of powder, heating or cooling, scraping and 35 cutting as before described'relating to the of said film and in Contact therewith, means for varying the temperature in order to solidify the film after the application of leaves and means for removing the prepared leaves.

2. In an apparatus for producing and prcparing leaves or foils from metal, a drum, areceptacle containing adhesive material, a roller dipping into said receptacle and adapted to spread said adhesive material in form of a film, a roller containing metallicl leaves, another roller adapted to bring said metallic leaves into engagement with said drum and means for varying the temperature in order to solidify the film after the application of said leaves.

3. Ina an apparatus for producing and preparing leaves or foils from metal, a drum, a receptacle containing adhesive material, a roller dipping into said receptacle and adapted to spread said adhesive material in form of a film, a roller containing metallicI leaves, another roller adapted to bring said metallic leaves into engagement with said drum and means for varying the temperature in 4order to solidify the film after the application of said leaves and means for removing the prepared leaves.

4;. In an apparatus for producing and preparing leaves orfoils from metal, a drum, a receptacle containing adhesive material, a roller dipping into said receptacle and adapted to spread the adhesive material in form of a film on the surface of said drum, a roller containing the metal leaves and a roller adapted to guide said leaves in direction of rotation of said drum and into engagement with the same, an additional roller for guiding paper-tape removed from said leaves, means for winding up the paper-tape, means for varying the temperature in order to solidify the film after the application of said leaves and means for removing the prepared leaves.

In testimony whereof I afiix my signature in presence of two witnesses.
